Hi guys, I need some assistance.
My 21" Sony Multiscan 500PS screen will suddenly not show other than text mode. I boot off a live LupuPlus-5.2.8, so there is no corrupted X.

I have a working text mode with the Sony, I can run Xorgwizard with no complaints, and when I run Xwin, I can hear the familiar sound when X starts and set the new resoultion.
After that: black screen, no mouse, no visible reaction from keyboard, and the screen's setup menu don't show until I use Ctrl-Alt-Backspace and get back to text mode again.

At first, I thought the ATI graphic card failed, so I tried several graphic cards of several brands, but with similar results. I then fired up my old 19" Intergraph screen using the original ATI graphic card in the PC, and everything is back to normal. I also tested the other cards with the Intergraph; PC is OK, graphic cards are OK and Intergraph screen is OK.
Sony is not OK

Does anyone have some insight into what may be wrong? Is anyone familiar with problems with this Sony?
